1.使用方便，編程簡單
采用簡明的梯形圖、邏輯圖或語句表等編程語言，而無需計算機知識，因此系統(tǒng)開發(fā)周期短，現(xiàn)場調試容易。另外，可在線修改程序，改變控制方案而不拆動硬件。
2.功能強，性能價格比高
一臺小型PLC內有成百上千個可供用戶使用的編程元件，有很強的功能，可以實現(xiàn)非常復雜的控制功能。它與相同功能的繼電器系統(tǒng)相比，具有很高的性能價格比。PLC可以通過通信聯(lián)網(wǎng)，實現(xiàn)分散控制，集中管理。
3.硬件配套齊全，用戶使用方便，適應性強
PLC產(chǎn)品已經(jīng)標準化、系列化、模塊化，配備有品種齊全的各種硬件裝置供用戶選用，用戶能靈活方便地進行系統(tǒng)配置，組成不同功能、不同規(guī)模的系統(tǒng)。PLC的安裝接線也很方便，一般用接線端子連接外部接線。PLC有較強的帶負載能力，可以直接驅動一般的電磁閥和小型交流接觸器。
